GUSTAF DE LAVAL, OF STOCKHOLM, SWEDEN.

MOTOR FOR CHURNS.

SPECIFICATION forming part of Letters Patent No. 368,327, dated August16, 1887.

Application filed December 28,1886. Serial No. 222,757.

To all whom, it may concern..-

Be it known that I, GUSTAF DE LAVAL, a subject of the King of Sweden,and a resident of Stockholm, Sweden, have invented certain new anduseful Improvements in Motors for Churns, of which the following is aspecification.

This invention relates to a device for driving churns by steam, in whichthe churn is mounted upon a shaft that is provided with a toothed wheelwhich gears with a worm upon the shaft of a steam reaction-wheel. Thepro portion between the worm and the toothed wheel is such that thechurn receives the required speed of rotation.

In the annexed drawings, Figure 1 represents the upper part of averticallymounted churn and the steam reactionwheel for operating it.Fig. 2 is a section of the reactionwheel at the line a: a:, Fig. 1. Fig.3 represents a horizontal churn and driving mechanism. Fig. 4 is alongitudinal section of the same; and Fig. 5 is a section at the line 3/y, Fig. 2, and elevation of the steam-wheel.

a is the stand or supporting-frame; b, the churn; 0, the shaft of thechurn, which is mounted in bearings upon the frame a; (Z, a toothedwheel upon the shaft 6; e, a worm mounted in suitable bearings upon theframe and gearing with the wheel (I; f, a casing surrounding this wormand containing its bearings; g, a steam reaction-wheel having curvedarms; h, a casing in which the steam reactionwheel or similar device isrevolved; i, the inlet-pipe for the steam passing to the arms of thereaction-wheel; k, the outlet for the ex- (No model.)

haust-steam; Z, a pipe for letting out the Water of condensation fromthe bottom of the casi ng h.

NVhen using the apparatus, a cock in thesteam-pipe is opened as much asnecessary and the steam rushes into the reaction-wheel and through itsarms and out against the air, causing it to revolve, and in turn thescrew connected upon its shaft is given a rapid rotatory motion, and theworm drives the toothed wheel 11 and causes the churn to revolve. Thechurn I) may be placed in a horizontal position, as in Figs. 3 and 4, orit may occupy a Vertical position, as in Fig. 1, the same devicesconstituting the motor being available to operate the churn in eitherposition.

I claim as my invention- 1. A motor for churns, consisting of thetoothed wheel (I, worm e, and their respective shafts, the steamreaction-wheel 9 upon the shaft of the worm, a pipe, 6, for supplyingsteam, and a case, h, surrounding the wheel, substantially as set forth.

2. A motor for churns, consisting of a toothed wheel, a screw-pinionmeshing therewith, and their respective shafts, a steam-wheel upon theshaft of the worm, and a pipe for supplying steam to the steam-wheel,substantially as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

GUSTAF DE LAVAL.
